I thought of that and even suggested GD to the folks
on the recent SMOT thread.
I looked everywhere for a GD sphere.  Not available.
Maybe a manufacturing problem'

make it lye flat on a slide and hold magnets close on each side it should do the trick.hope you have bar magnets for this.I've got this feeling that gadi will do much better than iron.compare distances with a nickel coin of similar size

@ekimtoor1,

                  Profit's is right about the dipole, both N and S poles, to achieve MCE in the Gadolinium. The magnetic strength required is 5 Teslas divided between the two magnets.That's the equivalent of 50,000 Gauss. Check the posted ratings.The magnets are rated in Gauss. All you need to do is couple them up additively to get the minimum required strength if they're too weak.

I will study that up. What is that in neos?

I set that pendulum experiment up and am uploading a video now.

Synchro'Profit's is right about the dipole, both N
and S poles, to achieve MCE in the Gadolinium. The
magnetic strength required is 5 Teslas divided
between the two magnets'

One pole also gives mce but seperate stage hot/cold as opposed to together hot/cold.any strength magnet will give this effect to various degrees.stronger gauss more effect.

@ekimtoor1

Magnetocaloriceffect:

"An increase or decrease of the temperature of a thermally isolated magnetic substance accompanying an increase or decrease in the intensity of a magnetic field".

Hi Ekimtoor1,

That Eulerian video magnification program is really cool.

If you go to this site:
http://people.csail.mit.edu/mrub/evm/#code

You can get the code in matlab and an executable to run offline. The code is really neat how it works, but won't go off topic with coding. :)

Still waiting for the order of gadolinium, hopefully by next week. I have a bunch of ideas to test. One is using infrared to heat the metal. Could surround it with a ring of 600-800nm leds and pulse it when it gets attracted to the magnet to see if it's enough to heat the material. Could also use a salt bottom to wick heat away. If the material is to dense for that then I have a couple of other ideas.

Keep experimenting.

@DreamThinkBuild,

The maximum heating from magnetic exposure takes place right at the Currie point of 68º. The Gadolinium should be attracted to the magnets, then heat up instantaneously and grow non magnetic on it's own with no additional heat.

Somebody has GOT to do the smot with this stuff someday.preferably at around 16-22 degree celcius room temp

I hung a coin as a pendulum suspended in the middle of 8 ferrite ring magnets. There was just enough attraction that if the pendulum swung off center any more than a few mm it would be pulled to the magnet.  Before I would say there was anything happening, I'd redo with something other than thread to eliminate the thread itself doing the twisting. And I'd put the whole thing in a jar to eliminate Air currents.
 
It looks like something is happening, the coin seems to start twisting a little from a dead stop. But I doubt it has anything to do with GD.  So I'm reluctant to post the video.

When using neos with the GD sample I have which is marked .999, the GD will not fall of at all never no matter what temp. I am able to reproduce the effect we are chasing with ferrite magnets. If the ambient temp is 67F the ferrite rings will just lift the 3.4gm GD coin. I then gently flow a lil hot air from a hairdryer and the GD will drop off. I cannot make this happen with a neo magnet.

I noticed GD is attracted to a neo with a strength similar to steel attracted to the ferrite magnet. So the attraction of GD to the ferrite rings I have is quite weak.

As profitis mentioned, the GD does not remain non-magnetic after reaching the curie point. It becomes diamagnetic sometime after the curie effect. Correct if I'm wrong please.

Yes gadi is very strongly paramagnetic above its curiepoint.strong magnets will still have strong attraction above the curie as we hardly notice the transition.if you attatch the coin to a school-ruler and swing that sideways through rows of neo's you may be able to see some smot effect ekim.the rigidity of the ruler will avoid sidewayswing.that small movement that you saw begin after dead-stillness of the coin is interesting and should be investigated further because it might have something to do with apophasis-oscillation.try this in other setups including hovvering closely over a single magnet pole.make the swing deadstill with your fingers and release.do this close to the mag and far from the mag (adjust heights)

Be sure to set up a "control experiment" at the same time. As you note, an observed twisting may or may not be due to the effect on specifically GD that is being examined, or specifically magnetism, etc. So you should set up an identical setup but with a suspended weight of something other than GD that has about the same density and shape (so size and weight and shape match as closely as possible to the GD setup). Does it twist under the same conditions as when the GD is observed to twist? If so then the effect is due to some other cause... which you should also try to control for, as you narrow down to the actual cause of the observed twisting.

It was the failure of the original claimant to do the proper control experiments that caused him to believe in "magnet perpetual motion" when he saw hard-drive magnets, suspended from a thread, twist always in the same direction. Unfortunately the original claim video by "ED" has been taken down, since he eventually acknowledged that my debunking experiments showed the true cause of the twisting. I don't know if he ever actually paid up the thousand dollars that he offered to any proven debunk; in the comments to my videos he agreed to do so by donating to his local animal shelter or spay-neuter program but I don't know if he did or not.
Here's the first of about 5 videos where I examine the claim and perform the _correct control experiments_ to show that the twist has nothing to do with magnetism and where I finally demonstrate its true cause:
