The downside is that the thicker the metals, the higher the power required to achieve ferromagnetism
. In the process, extra heat is generated.
These include a metal-insulator transition that is juxtaposed with ferromagnetism
, charge ordering, orbital ordering, polaron formation, electronic phase separation, and spin and charge stripes.
"In choosing a magnetocaloric material, you must select one with a Curie temperature--the temperature marking the transition between ferromagnetism
and paramagnetism--near the operating temperature of the cooler," said Karl Gschneidner, Marston Distinguished Professor at Ames Laboratory at the Iowa State University of Science and Technology.
But previous attempts to detect ferromagnetism
in clusters of normally nonmagnetic metals had failed.

to antiferromagnetism in iron-aluminum alloys.
Here, A-type antiferromagnetism (A-AFM) denotes ferromagnetism
within the ac plane and antiferromagnetism between planes, C-type antiferromagnetism (C-AFM) denotes ferromagnetism
between planes and antiferromagnetism within the plane, and G-type antiferromagnetism (G-AFM) denotes antiferromagnetism both within and between planes.
Recently, room temperature ferromagnetism
in ZnO doped with TMs has been studied both theoretically and experimentally [19-21].

Their topics include the thermodynamics of surface phenomena, localized states and surface elementary excitations, calculating adhesion characteristics of metals and their melts by the density functional method, friction of surfaces of solids with no lubrication, and ferromagnetism
in ultrathin films of transition metals.
The supramolecular coordination network based on octacyanomolybdates of the SAPR-8 configuration gives unique hopping paths and they must play a major role in realizing the photoreversible ferromagnetism
