The first experimental observation of piezomagnetism was made in 1960, in the fluorides of cobalt and manganese.

According to IEEE : " Piezomagnetism is the linear magnetomechanical effect analogous to the linear electromechanical effect of piezoelectricity.
3.
One is piezomagnetism, which consists of linear coupling between a magnetic field in a solid and a deformation ( analogous to piezoelectricity ).
4.
Piezomagnetism differs from the related property of magnetostriction; if an applied magnetic field is reversed in direction, the strain produced changes signs.
