arXiv preprint: Non-local magnon transport in the compensated ferrimagnet GdIG

https://arxiv.org/abs/1705.02871

With friends and collaborators at the Walther Meissner Institute (WMI), TU Munich we have written a paper about non-local magnon transport in Gadolinium Iron Garnet. The experimental measurements show quite a complicated behaviour where the non-local signal changing in response to both the external magnetic field strength and the temperature. We show that  different exchange magnon modes of the bulk change frequency in response to the field and temperature depending on their polarization in qualitative agreement with the measurements.

 

A reasonably comprehensive OSX backup strategy

It’s good practice to keep backups in different locations to guard against disasters like fire or theft. This is now becoming quite easy to implement using cloud backups. I also use multiple different pieces of software. This may sound a bit paranoid, but it mitigates against lots of nasty possibilities. For example nasty software bugs do happen which can render your backups useless. So there’s more chance of recovering if you have other fallbacks. Different software solutions can also incorporate nice features into your backup strategy such as reducing disruption for your work by having a 1:1 bootable copy of your hard drive.
Below is a brief outline of the different backup methods I’m using and some of the advantages they each bring to the party.
