【摘要】 <正>Ferromagnetic transition has been generally considered to involve purely an ordering of magnetic moment without any change in the host crystal structure or symmetry,evidenced by a huge wealth of crystal structure data from conventional x-ray diffractometry(XRD).However,the existence of magnetostriction in all known ferromagnetic systems indicates that the更多还原
