Sampler pack of all five ASYMFM probe varieties for Magnetic Force Microscopy (MFM), two probes of each. Each pack contains 10 probes in total.
Ideal for finding the best MFM probe for your research if the standard variety may not work.
f = 75 kHz | k = 2.8 N/m | tip coatings: CoCr, CoPt/FePt, permalloy
Two each of the: standard, high coercivity, low coercivity, high moment, and low moment ASYMFM line of probes, supplied in a single 10-probe pack.
Pick this sampler pack if you are new to MFM, or if you suspect your sample needs a probe with modified characteristics and you are not yet sure which. The standard ASYMFM-R2 addresses most applications well; however the four variants shift magnetic moment and coercivity low and high, so you can test each one on your own sample before committing to a full pack.

Variety
|
Best suited to: |
|
STANDARD |
General and all-around MFM. The right starting point for most samples. |
|
HIGH COERCIVITY |
MFM under an applied external field, where the tip must resist remagnetization. |
|
LOW COERCIVITY |
MFM in an applied field, where the tip should follow the field rather than resist it. |
|
HIGH MOMENT |
MFM on weakly magnetic samples where maximum signal strength is needed. |
|
LOW MOMENT |
Higher resolution MFM and/or where a standard tip's field would disturb the sample's magnetization. |
All five varieties share the same base probe: a silicon probe with a visible tip apex, nominal 75 kHz resonant frequency and 2.8 N/m spring constant. Only the magnetic coating differs. Full specifications for each variety are given on its own product page.
