A metal-in-gap (MIG) ferrite magnetic head has first and second core members (12, 14), having opposed faces (12A, 14A), and a material (30) providing a non-magnetisable transducing gap arranged between the opposed faces. A thin barrier layer (22, 26) of a refractory metal, and a layer (24, 28) of a material of high magnetic moment are provided between at least one of the opposed faces and the material providing the non-magnetisable transducing gap. The or each barrier layer is formed from tungsten or tantalum, and the or each layer of a material of high magnetic moment is formed from Sendust. |
