The screencast about NanoWorld AFM probes for Magnetic Force Microscopy held by Dr. Marco Becker has just passed the 1500 views mark. Congratulations Marco!
Magnetic Force Microcopy is a type of Atomic Force Microscopy in which a magnetised AFM tip is used to measure magnetic interactions between the tip and the surface of a magnetic sample. These detected interactions are then used to reconstruct the magnetic structure of the sample surface
NanoWorld currently offers two types of MFM tips:
– MFMR – This type of magnetic AFM tip is coated with a hard magnetic coating on the tip side and yields a very high force sensitivity, while simultaneously enabling tapping and lift mode operation.
– S-MFMR – These magnetic AFM tips are coated with a soft magnetic layer on the tip side and are designed for the measurement of magnetic domains in soft magnetic samples.
In their publication “Magnetization-polarization cross-control near room temperature in hexaferrite single crystals” V. Kocsis, T. Nakajima, M. Matsuda, A. Kikkawa, Y. Kaneko, J. Takashima, K. Kakurai, T. Arima, F. Kagawa, Y. Tokunaga, Y. Tokura and Y. Taguchi report that they have successfully stabilized a simultaneously ferrimagnetic and ferroelectric phase in a Y-type hexaferrite single crystal up to 450 K, and demonstrated the reversal of large non-volatile M by E field close to room temperature. Manipulation of the magnetic domains by E field was directly visualized at room temperature by using magnetic force microscopy.*
NanoWorld MFMR AFM probes with a hard magnetic coating were used for the magnetic force microscopy measurements described in this article.
