Contrasting the magnetic response between magnetic-glass and reentrant spin-glass
Magnetic-glass is a recently identified phenomenon in various classes of
magnetic systems undergoing a first order magnetic phase transition. We shall
highlight here a few experimentally determined characteristics of
magnetic-glass and the relevant set of experiments, which will enable to
distinguish a magnetic-glass unequivocally from the well known phenomena of
spin-glass and reentrant spin-glass.Comment: 10 pages and 4 figures. The preprint has been amended after taking
care of various typographical errors, some errors in Figs.2 and 4 and with
the addition of some new references. This version has been accepted for
publication in Physical Review
