Magnetic Glass formed by kinetic arrest of first order phase transitions
Abstract
Metallic glasses are formed by splat-cooling; this ensures that atomic motions are arrested before the latent heat of solidification can be extracted. Glass is defined as a higher disorder metastable state with arrested kinetics. Arrested kinetics is a defining property of a glass, rather than structural disorder as, e.g., in amorphous silicon [1]. `Magnetic glasses' identified recently possess structural as well as magnetic long-range order, but show relaxation and specific heat as for a structural glass [1]. The values of Tc and Tg in these materials are easily varied by varying the magnetic field H, allowing one to go from metallic glass to glass former like scenario.

Comments
Last paragraph of v2 is modified and expanded to address how studies on magnetic glass can help understand the physics of formation of structural glass, as distinct from jamming
