FIRST ORDER REVERSAL CURVES 7,752 Points: Elapsed Time - 11 minutes
First order curve (FORC) diagrams are a powerful new method for investigating hysteresis in magnetic systems. The AGM system hardware and software allows for the rapid and convenient acquisition of many data points for post processing.
Magnetically soft samples are readily analyzed utilizing the alternating gradient technique an example of which is displayed here.
Elapsed time 4.2 minutes @ 500 points
THIN FILM MEDIA Fe/KCoFe
The alternating gradient technique is the fastest, most sensitive method available for analyzing magnetically weak samples with fast switching transitions as shown here.
THIN FILM
GARNET
SLOPE CORRECTED
Thin film garnet represents another example of an extremely week sample with fast switching transitions. The alternating gradient technique is unsurpassed for its speed and sensitivity in such applications.
