FEATURES Measures remanent hysteretic properties in arbitrary directions on thin film media Auto mapping of ratio of remanent properties in circumferential and radial directions Measures time dependence of remanent coercivity Measurement principle same as that of RMM Radial measurement range (O.R. - 1.5mm) to (I.R. + 2.5mm) Hmax = 12 kOe Maximum Hcr > 6 kOe; minimum MrT = 0.04 memu/cm^2 Absolute uncertainty in MrT = 0.05 memu/cm^2 or 5% (whichever is larger) Absolute uncertainty in Hcr = 50 Oe or 5% (whichever is larger) Vacuum chuck No restrictions on disk size [27-130mm] Same simple, adjustment-free operation as RMM© 115 V, 50/60 Hz, 15 A; 90-100 p.s.i. compressed air Unit On Casters, Totally Mobile

Spatial dependence of Mrt O.R. in 95mm disk

In the following figures each data point is represented by a pair of numbers (11) indicating that the data refers to the first measurement radius and the first measurement angle. Multiple measurement points can be programmed.

Mrt O.R. as a function of angle for anisotropic disk

Hcr O.R. as a function of angle for anisotropic disk

Mrt O.R. as a function of angle for isotropic disk

Hcr O.R. as a function of angle for isotropic disk
