But there was another link on that page that went here:

Warning! The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.

Photoelectromagnetic Effect

Anything that starts off with a warning like that is immediately suspect, just like all of the Soviet era "science experiments" that ended up on the front page of tabloids all around the world. The "ideological bias" of things like the Great Soviet Encyclopedia was that Soviet scientists were threatened with a trip to Siberia if they didn't have something published, so they published all kinds of scientific mumbo jumbo, just to save their own lives. Can't say I blame them, but that doesn't make it true.

I would venture to say that if it were true or economically viable, someone would be exploiting it outside of being mentioned in Soviet era "Publish-or-die" rags.

The most I've heard of in terms of PEM sensors has been in a slew of various patents and published papers. I'm not certain anyone has started to manufacture anything utilizing that technology.

Anyways, here's some links:

What is the Photoelectricmagnetic effect?

Is it possible you're looking for Photoelectric sensors?

Are they used on magnetorestrictive-hydrodynamic drives, to control cavitation and hydraulic comprehension?

If you bothered to read the link in the previous post you'd know that...

The photoelectromagnetic effect is used to construct highly sensitive microwave and infrared detectors with a low time constant. Such detectors are employed in radio astronomy, space studies, spectroscopy, and passive radar.

All Soviet children know this.

That´s a good question! Can be used for many things I guess...

It is a mode of operation for certain semiconductor´s (e.g- germanium and [this one seams very exquisite-oxide of copper], that when with a magnetic field and exposed to light they form electric potential.

no number´s nor formulas! ence the question!

for the rest of the poster´s, know that I knew about this fenomena in a American Electronic course, so no politic´s here in issue! and know that there are excellent scientific book´s made in Russia!

So gentleman´s, there is not a sensor of this type made at industrial scale?

Bespoke is still on the industrial scale.

Which end are you talking about?

you know that my mate bone_z as not quite a certain idea in mind... but, by the way, can you tell me what is Bespoke - is it a person?

Bespoke

Most things start off that way.

I am most sure that was not the idea of bone_z! more like a form of id machines...

id machines...interesting concept. Could get weird The id doesn't care about reality, about the needs of anyone else, only its own satisfaction.
