Abstract:
We have studied the effect of a weak magnetic field ($\sim$10$^{-3}$–10$^{-2}$ T) on the elastic and inelastic characteristics of a diamagnetic beryllium condensate. It is established that the field effect is most pronounced in a magnetic aftereffect, which leads to inversion of the amplitude and temperature dependences of the effective shear modulus at an almost unchanged level of the elastic energy absorption.
