VIBRATING LARGE SAMPLE MAGNETOMETER BIGGEST SAMPLE SIZE OF ANY COMMERCIAL VSM

• Measures samples up to 6" in diameter (larger sizes possible)
• No restrictions on substrate composition/thickness
• Vacuum chucks for different sample sizes/shapes
• Air core solenoidal fields to 1.5 kOe uniform to within 2% across 6" sample
• Transverse field coils available
• Minimum field step = Hmax/4096
• Hysteretic properties on soft and moderately hard samples
• MR response (AMR, GMR) on soft films and spin valves
• 90 Hz vibration frequency
• Automatic analysis of spin valve loops
• 32 sec for complete hysteresis loop
• Noise floor=0.015 memu/cm^2 with 10 msec time constant
• Monolayer sensitivity
• 360 degree sample rotation
• Power, cooling requirements dependent on field configuration
