摘要

EPR studies of VOSO₄·5H₂O revealed that, on reactor neutron irradiation, it exhibits magnetic order and regions of spin glass behavior which is persistent even up to 473K. This is attributed to dehydration of the compound together with homogeneous incorporation, in the lattice, of chromium produced due to nuclear reaction ⁵¹V (n,β) ⁵²Cr. Experiments with gamma irradiated and heat treated samples doped with chromate, have given strong support to the role of chromium in inducing the magnetic order.
