The angular dependences of coercivity and critical field were calculated with the consideration of the uniaxial magnetocrystalline anisotropy, the shape anisotropy, the interaction anisotropy of the ellipsoids, as well as the number of ellipsoids. This model could be used to explain the magnetization reversal mechanism of the oriented Ba ferrite particulate media. %K magnetization reversal %K model of a chain of oblate ellipsoids
