Session questions:
  1. Which is the size of the sensor?
  2. What can you tell about the temperature dependence of AMR in LSMO?
  3. Do you perform annealing on your samples?

We kindly ask the speakers to reply to any questions left unanswered during the talk.

Which is the size of the sensor?
Wheatstone bridge arms are 300um x 100um, so device is 500um x 500um plus gold pads for electrical contact. Size effects will be investigated.

What can you tell about the temperature dependence of AMR in LSMO?
In the sample temperature range that AMR measurements were performed, no significant variation of MR ratio was verified, until sample reaches Tc and loses magnetic response.

Do you perform annealing on your samples?
No.
