The XY pyrochlore AFM:spin dynamics upon rare-earth dilution in Er2Ti2O7 (CON...
Er2Ti2O7 constitutes an experimental realization of the <111> easy-plane pyrochlore AFM and orders at 1.1 K into the theoretically predicted spin structure. However, the... -
Neutron reflection from 3He layer adsorbed on liquid 4He surface
More than four decades ago A. F. Andreev predicted theoretically the existence of quantum states of 3He atoms on free surface of liquid 4He . In other words, at low...
