Abstract: | Switching thresholds of plated wires were determined with slowly applied external magnetic fields, using both torquemeter and ac techniques. The samples included wires having helical easy-direction angles of 0°, 24°, 30°, and 60°. A study was made of the dependence of switching threshold HCon the angle θ between applied field and wire axis. Good agreement was found with the relationH_{C}(theta)=H_{C}(0)/cos thetafor all helical angles and for θ as high as 85°. It is concluded that with the cylindrical film geometry only the axial component of external field is effective in quasi-static switching over wide ranges of field direction and helical angle. |
