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...

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...

Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...
