[f(k)] Mathias Kläui (Mainz): Antiferromagnetic spintronics: spintronics without magnetic fields, in the physics colloquium - with the Physicist' club, including Colloquium sauna in the evening with free pizza and beer!!

Tue Oct 31 14:55:33 EET 2023

Hyvää lokakuun viimeistä viikkoa arvon fyysikkokerhon jäsenet! Happy last week of october dear members of physicist' club! Eng. below

Olette varmaan jo huomanneet fysiikan laitokselle levitettyjä postereita perjantaista 3.11, jolloin on tarjolla ilmaista kaljaa ja ilmaista pitsaa. Nanosaunalla klo. 16.00 alkaen kollokviosauna-teemalla.

Perjantaina 3.11 on siis ensin aamupäivällä fysiikan kollokvio klo.10 alkaen fys1:ssä, jonne fyysikkokerho on valinnut puhujan ja aiheen (Mathias Kläui - Antiferromagnetic Spintronics: Spintronics without magnetic fields). Esitys on suunnattu kaiken tasoisille henkilöille ja opiskelijoille. 

Kollokvion jälkeen iltapäivällä on kollokviosauna klo.16 alkaen nanosaunalla, jonne Mathias Kläui tulee pitämään lyhyehkön esityksen urapolustaan noin klo.17.00, jonka jälkeen osallistujille on tarjolla ilmaista pitsaa ja kaljaa (sekä muuta juomista) saunan ohella. Varaathan saunaan oman pyyhkeen sekä uimavaatteet sillä tarjolla on vain sekavuoroja, uimapuvulliset klo. noin 18.00 - 19.00, kaikki 19.00->.

ENG.

You have probably already noticed the posters distributed at the physics department from Friday 3.11, when free beer and free pizza are offered. In the nanosauna starting from 16.00 with a colloquial sauna theme.

So on Friday 3.11 there will be a physics colloquium first thing in the morning starting at 10 a.m. in fys1, where the Physicist' Club has chosen the speaker and topic (Mathias Kläui - Antiferromagnetic Spintronics: Spintronics without magnetic fields). The presentation is aimed at people and students of all levels.

After the colloquium, there will be a colloquium sauna in the afternoon starting at 16:00 in the nanosauna, where Mathias Kläui will give a short presentation about his career path at around 17:00, after which the participants will be offered free pizza and beer (and other drinks) along with the sauna. Please reserve your own towel and swimwear for the sauna, as there are only mixed shifts available, those in swimwear at around 18.00 - 19.00, all 19.00->.

Lämpöisin terveisin // Warm regards

Welcome to the University of Jyväskylä physics colloquium. This week's colloquium is organized together with the Physicist club [https://www.jyfk.fi/en/] (Fyysikkokerho [https://www.jyfk.fi]), who has selected the topic and the speaker.

On Friday 3rd November at 10 am in FYS1 and Zoom [https://jyufi.zoom.us/j/66703175507] (passcode 890524):
Mathias Kläui, Gutenberg University of Mainz and NTNU Norway:
Antiferromagnetic Spintronics: Spintronics without magnetic fields
While known for a long time, antiferromagnetically ordered systems have previously been considered, as “interesting but useless”. However, since antiferromagnets potentially promises faster operation, enhanced stability and higher integration densities, they could potentially become a game changer for new spintronic devices such as magnetic memories. Here I will show how antiferromagnets can be used as active spintronics devices by demonstrating the key operations of “reading” [1], “writing” [2], and “transporting information” [3] in antiferromagnets. Beyond conventional collinear antiferromagnets, more complex non-collinear antiferromagnets exhibit a range of exciting properties including higher – order Hall effects that we have recently studied [4].
