摘要：

Neutron depolarisation studies and Lorentz transmission electron microscopy (LTEM) observations of domains structure of R-S.G. FexZr100-x with 89 less-than-or-equal-to x less-than-or-equal-to 92 are reported. From LTEM it is seen that the domains appear at 260 K (for x = 89) in agreement (within +/- 5 K) with the Curie temperature T(c) determined from magnetic measurements. As the temperature is further decreased below T(f) (the ferro-spin-glass transition temperature) the domain structure stays practically unchanged. Neutron eepolarisation measurements confirm these results and reveal that a kind of domain structure persists down to x = x(c) (almost-equal-to 94), the multicritical concentration.
