He headed the Departamento de Física at the Facultad de Ciencias, Universidad de Chile, in 1969. He returned to head it again in 2014. Forty-five years passed between the two, and the department — which he himself had helped found in 1965 — was still running.

In between, he did the theoretical work on magnetism that earned him the Premio Nacional de Ciencias Exactas 2007 (Chile's national prize for the exact sciences).

01 — The physics

What "exchange bias" is, and why it matters

When a ferromagnetic material is placed in contact with an antiferromagnetic one, the former becomes "pinned": its response to the magnetic field shifts, as if it retained a memory of a preferred direction. That phenomenon is called exchange bias, and it is what allows the magnetic reference to be fixed in hard-disk read heads.

Kiwi's theoretical work explaining that coupling is his most-cited contribution. In 2007, when he received the Premio Nacional, his research on the subject had 162 citations and placed him in the top 1% of his field according to the Essential Science Indicators.

Professor Kiwi's outstanding work in developing physics in Chile, in training many doctoral graduates in condensed matter physics, and for the profound impact of his research into the "exchange bias" phenomenon in magnetism

03 — Honesty

What the sources do not quite settle

Documented

He helped found the Departamento de Física at the Facultad de Ciencias in 1965 and headed it in 1969-1970 and 2014-2018.

Recorded by the department itself.

Documented

He received the 2007 Premio Nacional de Ciencias Exactas by unanimous decision.

The jury's verdict matches word for word between the Universidad de Chile profile and Emol's coverage.

Likely

He was born on 19 June 1938 in Santiago.

The exact day appears in the Spanish-language Wikipedia; institutional sources imply it through the age they attribute to him in 2007.

Unconfirmed

A 2007 press article places him in the Departamento de Física at the Universidad Católica.

This contradicts every other source, which places him at the Universidad de Chile from 1962. It is almost certainly an error in that article, but it is recorded here nonetheless.

Unconfirmed

This page does not quote his own words.

No direct verbatim quotation from Kiwi was found in the accessible sources. Rather than attribute phrases to him, it seems better to say they are missing.
