Measurements of magnetic disaccommodation in single yttrium iron garne
t (YIG) crystals are presented, Two peaks of 0.2%-0.3% are observed in
the isochronal spectrum around 130 and 250 K. Comparison of our resul
ts with those on polycrystalline MG samples and with similar data on i
lluminated and gamma ray irradiated single YIG crystal samples is prov
ided. (C) 1996 American Institute of Physics.
