I have created a proof of concept page at [https://mtuner.github.io/sc-magnetic-poc](https://mtuner.github.io/sc-magnetic-poc). It intentionally produces a very distinct CPU activity pattern while measuring magnetometer using the Sensor API, and shows the recorded values.
We have not published the code from the paper yet, it is planned but may take some time.

Regarding the AbsoluteOrientationSensor, we have not investigated it in detail, a quick test similar to the PoC page does not show visually noticeable influence. I would assume that disturbance caused by the CPU is not strong enough to significantly affect a sensor fusion.
