Can you give me some advice about the data fluctuation problem in the Hall resistance measurement using PPMS?

In our Hall resistance measurement using PPMS DC resistance model with four probe method, we always encounter a problem that the resistance data randomly fluctuates, so we must remeasured a same...

The mobility determination when there exists anomalous hall effect?

It is well known that the mobility is always determined through standard Hall effect detection. For an ordinary Hall effect, that is easy to extract the hall coefficient. However, if the system...

Why is the anomalous hall conductivity defined as -Rxy/(Rxx*Rxx+Rxy*Rxy) but not 1/(Rxy-Rxyoh)?

Where R notes resitivity, Rxyoh represents the Rxy part coming form the ordinary Hall effect.

How to treat the as received LaSrAlO4 and MgO substrates to get smooth surface with steps?

It is well known that a smooth substrate with step surface is important for growing epitaxial films. Recently, I encountered this problem on LaSrAlO4 and MgO substrates. I have tried H3PO4 etching...

Could spin orbital coupling form in a perfect crystal without inversion symmetry structure?

In my knowledge, near all of the publications say the spin obtial coupling originates from the moving of a spin electron relative to a atom, and there are two mechanisms to induce SOC, i.e. the...

Strange result of a negative film temperature enhancement in 3 omega method measurement

We recently used the 3 omega method to detect the thermal conductivity of a film with about 100nm thickness on a STO substrate with thickness about 500um. In the detection, we strangely found the...
