Abhishek Viswanath

Dear Ernst Lenz Thank you for the suggestion. Will go through :)

Muhammad Shahbaz Anwar

Following paper may help you,

Article Anisotropic magnetothermoelectric power of ferromagnetic thin films

Dear Muhammad Shahbaz Anwar Thank you.

It looks so good.

Could you kindly tell me how the output voltages were measured. Are there any special modifications made while connecting to the nanovoltmeter,I wasn't able to figure out the same?

Thanks.

Dear Abhishek Viswanath

We used nanovoltmeter in proper measurement range. I am sure you already noticed that we fabricated a Seebeck sample holder based on a PPMS puck. We connected two Au wires (you can also use Cu or Al wires) using pressed In, puck was connected with PPMS (of course in vacuum) and PPMS/puck were connected to external electronics like nanovoltmeter and temperature controllers.

Please let me know if you have any other question.

Dear Muhammad Shahbaz Anwar Thanks.

Yes.

So I interpret that you have purchased Physical Property Measurement System from Quantum Design and installed the homemade setup over it as well-illustrated?

https://www.qdusa.com/siteDocs/productBrochures/1084-500_PPMS_TTO.pdf I assume the designed prototype is to replace this unit.

Hi, Abhishek Viswanath

Yes, our design is simple and economical :). Temperature of hot side of sample holder was controlled externally while cold side temperature and voltage measurements were done by using internal electronics.

Muhammad Shahbaz Anwar interesting!
