摘要：

We report the observation of a field-induced transformation from the easy-plane antiferromagnetic structure to the easy-axis ferrimagnetic structure in a single crystal of TbFe4.4Al7.6 (tetragonal ThMn12 structure) at 5 K. Such a field-induced, irreversible transition has been identified. This transition is accompanied by a giant orthorhombic distortion: epsilon(aa) = - epsilon(bb) approximate to 3.5 x 10(-4) that is associated with a magnetic hardness (mu(0)H(C)approximate to3 T) that is unprecedented in this category of materials.
