Abstract
Magnetic hysteresis studies were carried out on Metglas 2605 Co(Fe67Co18B14Si1) samples, cut parallel and perpendicular to the ribbon axis and annealed at different temperatures. The samples annealed at 450°C for 2 hr show a coercive force of 8·75 Oe and 0·60 Oe in the parallel and perpendicular directions respectively. Electron probe micro analysis studies revealed the onset of primary crystallization at 400°C and a gradual displacement of B and Si from the lattice as the annealing temperature was increased to 450°C. The observed large coercive force is due to an increase in anisotropy resulting from an intergrowth pattern of the type Fe x Co1 −x , 0·3<x<1·0, including boron containing phases such as (FeCo)B, (FeCo)2B, (FeCo)3B, developed by the displacement of and Si from the original amorphous lattice.
